Hello again Bob, I hope all is well,
Thanks again for your assistance and advice, the Denon avr789 is the best Receiver I've tested, and at the price I purchased it at, it's a no brainer I'm keeping the Denon & returning the Pioneer vsx919, I spent a decent amount of time tweaking it and so on, it's not as complicated as reviews make it sound, definitely a great buy! thanks again for all your help!!
take care
Justin
